I totally see what you are saying.
I kinda did the same as well.
I bought on Ebay for $830 incl. shipping:
Mac Pro 4.1
2 x 2.26 Ghz Quad Core
16 GB DDR3 1066 Mhz (4x4 GB)
GT120 512 MB GDDR3
250 GB 7200 RPM Samsung HDD
I have now spend a total of $1555 and my system looks like this now:
Mac Pro 5.1
2 x 2.93 Ghz Quad Core (X5570)
48 GB DDR3 1066 Mhz (4x4GB + 4x8GB)
GTX 570 2.5 GB GDDR5 + GT 120 512 MB GDDR3
Intel SSD X25M 160 GB SSD (OSX, Applications)
1 TB WD Green (Storage)
250 GB 7200 RPM Samsung HDD (Windows for Bootcamp)
CrossOver 290M 29 Inch IPS (2560x1080) Monitor
Wireless Apple Keyboard
Wireless Apple Mouse
I feel like I've got a lot of computer for a total of $1555...
Most expensive upgrades was for sure the Monitor and extra 32 GB memory...
But good luck!
You can do an inquiry on some sellers if you can just get the Mac Pro without the CPU and ram even though it's not specified in the listing. You best choices would be from sellers who sell Mac Pros as a business as they may have spare units. No harm in asking.Yeah I just want something reasonably inexpensive because I'm going to be in possession of 2 xeon hexacore westmere CPUs pretty soon. I figured I could just stick it in there and add ram to it and it would be ready to rock.
So far I haven't seen anything like that on eBay.
